SPOOL, REEL, BOBBIN, AND THE LIKE.

Application jlled March 1, 1926.

Fig. 1 is a perspective view of one form which a spool embodying my invention may assume.

Fig. 2 is a view thereof in central longitudinal section.

Fig. 3 is a similar view of another form of spool embodying my invention.

Fig. 4 is a similar view of still another form of spool embodying my invention.

My invention relates to an article of manufacture which may properly be identified by any one of a number of synonymous or correlated names, such as spool, reel, bobbin, roll, beam, quill, etc., all of which are intended to serve as holders or supports for such commodities as wire, thread, yarn, cordage, filaments, ribbons, note-sheets, or webs of flexible material. The articles so named may be fundamentally the same with respect to construction and function, the difference being rather a matter of size and the relative proportions of their component parts. For convenience in describing and claiming my invention, as I may now state, I shall use the word spool in a broad eneric sense to cover all of the devices above listed and all other devices of kindred nature and use.

The object of my invention is to produce, at such a low cost for manufacture that it may be discarded after a single service if desired, a rugged, lightweight, skeletonized spool having a mandrel-receiving bore of relatively small diameter as compared to the diameter of its barrel, and characterized by smoothness and freedom from cracks at the junction of its barrel and end-flanges whereby the spool is adaptable for the reception of fine-size wire and thread without injury thereto. t

A further object of my invention is to provide a skeletonized spool having endflanges of suflicient rigidity as to effectively 'defy distortion in ordinary usage and of suflicient width to facilitate stacking and thus prevent injury to the commodity wound thereupon by the flanges of adjacent spools. With these objects 1n view, my invention consists in a skeletonized spool characterized by having a barrel provided with endflanges built up of substantially coaxial superimposed convolutions of flexible sheet material, and a core-tube located within the said barrel, parallel therewith, and spaced therefrom by spacing-flanges.

Serial No. 91,357.

My invention further consists in a spool characterized as above and having certain details of construction and combinations of parts as will be hereinafter described and particularly recited in the claims.

In carrying out my invention as shown in Figs. 1 and 2 of the drawings, I employ a barrel-tube 5 having end-flanges 6, and a core-tube 7 arranged centrally within the said barrel parallel therewith and connected thereto by spacing-flanges 8. The barrel 5, end-flanges 6, core-tube 7 and spacingflanges 8 are each built up of substantially coaxial superimposed convolutionsof flexible sheet material such as paper, fabric or any other suitable material which may be properly described as flexible sheet material. Preferably these convolutions are mutually adhered by a waterproof adhesive such as shellac or phenol resins; though other means may be employed.

In Fig. 3 of the drawings, I have shown a spool having the same elements as that shown in Fig. 2 but in this instance the barrel 5 and core-tube 7 are not formed of convolutions, but may be of Wood, metal or composition. The end-flanges 6 and spacing-flanges 8, however, correspond to the similar parts of the spool shown in Fig. 2, in so far as they are built up of substantlally coaxial, superimposed convolutions of sheet materiah Fig. 4 shows a spool corresponding to that shown in Fig. 3, but having in'addition, an intermediate spacer 9 of superimposed convolutions, extending between the barrel 5 and core-tube 7 of the spool structure. Under the construction just described I am enabled to'prevent the appreciable bending of either the barrel or core-tube in the event that they should be relatively thin material considering the load imposed upon them or if the spool structure should require this additional supporting member owing'to its length or for any other reason.

Under my invention, therefore, I am enabled to produce at low cost, a spool which is both ight in weight and of rugged facture, the consumer of such commodities as may be installed upon my improved spool, may after, removing the commodity, discard the spool if'de sired, rather than being forced to return it to the shipper for credit. as has generally been the practice in the past,

tendin owing to the high cost of the spools of the prior art.

Furthermore, the light weight of my improved spool effects an appreciable saving in transportation charges and its relatively broad flanges, by facilitating stacking prevent injury to the commodity installed upon it. This injury has been often occasioned by the flanges of one spool slipping out of alignment with those of an adjacent spool with resultant damage to. the contents of the spools.

I claim 1. A spool having a tubular barrel, a coretube positioned therein, spacing-flanges extending between the said barrel and the said core-tube, and end-flanges for the said barrel, the said end-flanges being composed of substantially coaxial superimposed convolutions of sheet material.

2. A spool having a tubular barrel, a coretube positioned therein, spacing-flanges exbetween the said barrel and the said core-tu e, and end-flanges for the said barrel, the said end-flanges being composed of substantially coaxial superimposed convolutions of sheet material mutually adhered.

3. A spool having a tubular barrel, a coretube positioned therein, spacing-flanges ex tending between the said barrel and the said core-tube, and end-flanges for the said barrel, the said end-flanges being composed of substantially coaxial superim osed convolutions of sheet material mutua ly adhered by a waterproof adhesive.

4. A spool having a tubular barrel, a coretube positioned therein, spacing-flanges ex tendin between the said barrel and the said core-tu e at the opposite ends thereof and intermediate the ends, and end-flanges for the said barrel, the said end-flanges being composed of substantially coaxial superimposed convolutions of sheet material.

5. A spool having a tubular barrel, a coretube positioned therein, spacing-flanges extendin between the said barrel and the said core-tu be, and end-flanges for the said barrel, the said end-flanges and spacing-flanges being composed of substantially coaxial superimposed convolutions of sheet material.

6. A spool having a tubular barrel, a coretube positioned therein, spacing-flan es extending between the said barrel and t e said core-tube, and end-flanges for the said barrel, the said barrel, end-flanges and spacingflanges being composed of substantially coaxial superimposed convolutions of sheet material.

7. A spool having a tubular barrel, a coretube positioned therein, spacing-flanges extending between the said barrel and the said core-tube, and end-flanges for the said barrel, the said barrel, core-tube, end-flanges and spacing flanges being composed of substantially coaxial superimposed convolutions of sheet material.

In testimony whereof, I have signed this specification.
